Shops selling on Shopee or Lazada often find that after running Facebook ads to drive people to their shop, they can't tell how many sales the ads generated, because orders happen in the marketplace app rather than on the shop's own website. CPAS, or Collaborative Performance Advertising Solution, is the tool that connects this data.

How does CPAS work?
CPAS is Meta's Collaborative Ads format, which uses your marketplace shop's product catalog to show ads on Facebook and Instagram. When people click, they go straight to the product page in the Shopee or Lazada app, and the marketplace sends product view, add-to-cart and purchase data back so the shop can see it in Ads Manager.
The benefits of CPAS
- 1Measure sales from ads for real, without guessing
- 2Retarget people who viewed products or added them to cart in your shop but didn't buy
- 3Use dynamic ads to automatically show each person the products they're interested in
- 4The system learns from real purchase data, so it finds buyers more accurately
Which shops is it right for?
It suits shops with many products that sell mainly on marketplaces, such as fashion, beauty, homeware and supplements. Shops with only a few products might start with regular ads first. Eligibility requirements differ by marketplace, so check with the platform or an agency before you start.
What to prepare before you start
Prepare your marketplace shop account and Meta Business Manager account, and check that product images and names in your shop are clear, because dynamic ads pull this information directly. If product images are poor or names are long and hard to read, the ads won't be appealing to click either.
Summary
CPAS lets marketplace shops run Facebook ads based on data, seeing how much each baht generates in sales and using that data to make campaigns more cost-effective over time.
